Embodiment Construction

[0043] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0044] The embodiment of the present disclosure provides a lost packet retransmission method, which is applied to the sending end, such as figure 1 As shown, the packet loss retransmission method includes the following steps:

[0045] 101. Acquire the SAK control message sent by the receiving end.

[0046] The SAK (window synchronization confirmation) control message includes at leas...

Abstract

The invention provides a packet loss retransmission method and device, and a storage medium, relates to the technical field of data transmission, and can reduce the problem of packet loss in existingUDP transmission. According to the specific technical scheme, the method comprises the steps of obtaining a window synchronization acknowledgement SAK control message sent by a receiving end; obtaining a first data packet corresponding to the packet serial number of the first data packet, and adding the first data packet to a packet loss queue of a sending end; detecting whether the data packet inthe target range has packet loss or not; when it is detected that a second data packet within the target range is lost, adding the second data packet to a packet loss queue of the sending end; and sending the data packets in the packet loss queue to a receiving end. The present invention is used for packet loss retransmission.

Description

technical field [0001] The present disclosure relates to the technical field of data transmission, and in particular to a lost packet retransmission method, device and storage medium. Background technique [0002] In order to improve the transmission efficiency, the video frame will be transmitted by UDP (User Datagram Protocol, User Datagram Protocol). However, UDP is an unreliable transmission protocol. After the data packet is sent, it is impossible to know whether it is safe and complete. Arriving at the receiving end, therefore, in this case, if there is packet loss, it will cause the video screen of the receiving end to be blurred. Contents of the invention [0003] Embodiments of the present disclosure provide a packet loss retransmission method, device, and storage medium, which can reduce the problem of packet loss in existing UDP transmission. Described technical scheme is as follows: [0004] According to the first aspect of the embodiments of the present disc...
